.They may discharge material .to any HO L 1 suitable chute or bin or aplurality of chutes and bins diagrammatically shown as F10, the detailsof which form no part of the present invention.

The usel and operation are as follows:

The mixed coal, as it passes for example from the right, is dischargedby the chute or spout B1 over the lump deck. All but the lump passesthrough the screen B2, yand the lump maybe picked, Vwhen necessary, asit pasesvover the section preceding the lateral extension of the eggandVV nut picking troughs. It passesthe'nce down the inclined section B3and thus to the conveyor.VVA

l TheV finer coal which lpasses. through the of my invention `screen B2travels across the screen C1 inthe egg 'deck `and theegg isthereby'separated,

the finer coal continuing on therethrough.`

The egg passes forwardly and is picked in the laterally positionedpicking troughs C8 and C12 the material from CB finding its way to thebottom deck D the material passing along C12 passing directly toY theterminal area B5. The screen El permits the passage .of the ylinermaterial but retains the nut,

which is similarly picked along the sections 'E8 and E and similarl ffinds its wa to the deck D or terminalportion B5. The material on vthedeck -D passes on beneath the hinged or adjustable portion B4 andis'discharged down the chute B6 with the rest of the coal. Any suitabletake-olf means may be provided, where necessary, to eliminatey the neswherethat is--desired Otherwise the entire volume of coal, except for`the material picked out of it, is discharged to the lconveyor B7.

As the varioussizes of coalV pass along the various pickingy troughs thestone and the bone are dropped in the various disposal chutes providedtherefor. The stone chutes all discharge to one si de of thespoils'troughs and the bone to the other and the classified Vmaterialspass toward the feed endl of the screen and are deposited in anyYsuitable Ypossible to put a maximum number of pick- .ers on a givenvolume of coal and greatly reduces the amount of'bone and stone whichescapes the pickers. The selective or classify` ing feature of thespoils trough enables -me to dispose of'two types of picking refuse ,orof rejected material, without re-classication, re-picking orre-s'creening.

In eect-I divide the material by screening, into a plurality of streamsof diderent ture. Y Y
